IMO the suspect might be 526748b925185e95f1415900ee13c2469d4b64cc.

My idea is that if you reboot without completely stopping the pc the
mouse stays connected in the "high res" wheel mode which hid-multitouch
can not handle. However I don't think the bolt receiver is supported in
either hid-logitech-dj.ko nor hid-logitech-hidpp.ko.

In addition to Jiri's requests, could you also post the dmesg after the
fresh (and broken) reboot, and after unplug/replug the dongle? We would
get more information on to which kernel modules are involved this way.

Cheers,
Benjamin
